System dialog boxes don't show in Plasma

[nhaehnle]

Does this issue occur when all extensions are disabled?: Yes

• VS Code Version: 1.94.2 (installed from Snap)
• OS Version: Ubuntu 24.04.1

Steps to Reproduce:

1. Perform any action that usually shows a "native" dialog box. For example
   • Help -> About
   • Add Folder to Workspace
2. Most of the time, the expected dialog simply doesn't show up

This is running in Plasma (default packages from Ubuntu), and I did receive a "kdialog crashed" notification once while poking at this.

Looking at ps output, there are a bunch of kdialog processes seemingly stuck in the background like this one:

  14629 ?        Sl     0:00  |   \_ kdialog --attach=23068718 --title=Add Folder to Workspace --multiple --separate-output --getexistingdirectory /home/nha

Running the command line from the ps output works fine, i.e. it shows the expected dialog box and prints the selected directory to stdout.

I was able to work around it by setting the "Window: Dialog Style" to "custom", but obviously that's not ideal.

Let me know if there's a way I can help by collecting more information.

I was able to work around this as well in Kubuntu 24.04 (KDE Plasma 5.27.11, VS Code from Snap), but only by enabling the Simple Dialog setting under Text Editor, then Files. The "Window: Dialog Style" setting had no effect for me.

I'm not able to verify the precise version of VS Code I have installed through Snap because the dialog won't open in VS Code to show me and the terminal (snap list) lists the version as "384ff738" with 172 under the revision column.

Edit: I also seem to be experiencing some kind of crazy memory leak related to this, as the kdialog process was using over 10 GB of memory.

Edit 2: Here's my current version info. Issue still persists, but it turns out you can still get your version info as long as you don't try to use the save dialog first:

Same here (kdialog version 23.08.5, vscode version 1.94.2 x64) The workaround mentioned by @nhaehnle (File > Preferences > Settings > Text Editor > Files > Simple Dialog > Enable) works fine for me. Thank you very much.

same for me, vcode version 1.94.2 x64 (from snap). Kdialog takes a lot of memory, and I can't open any folder from code (trick simple dialog: enable works) up-to-date Kubuntu 24.04 plasma: 5.27.11 kde frameworks 5.115.0 QT 5.15.13 graphics platform X11

I get this when trying to "Open Folder" or "Open File". Kdiolog eats one CPU core while ramping slowly up to ~20 GB of memory before crashing.

"Simple Dialog" is usable as a workaround.

The same problem here, after an unsuccessful attempt to install aspose-cad and cadquery. Kubuntu 24-04 lts and python 3.12. "Simple Dialog" is usable as a workaround.

Same problem here. Now I'm using the "Simple Dialog" trick.

Previously when I hit this it was on nightly. Now I'm hitting it on stable:

This could be the same problem as in https://github.com/microsoft/vscode/issues/230679, no?
